So most likely I'm just over reacting but I have so many things that set off my hypochondria. Like for instance when I walk or run I get a clicking in the top of my head that I can feel and hear. If I have a cold or something like a flu I'll be convinced that I have Lung cancer or HIV. I know it's stupid but this is honestly taking over my life and I'm scared about my health all the time. Anybody have any ways of coping or advice?

I have the same issues in my mind. I am always on google if I hurt somewhere. This is also part of anxiety, and I have found that yoga helps. It is something that can take your mind off bad things we think. Another thing that might help you clear your mind is a lavender bath. Soak in the tub in lavender and light lavender candles. This calms your mind. I hope that helps you.
